Title: Driving system of step motor for watch
Inventor: KATOU YOSHIAKI
IPC: H02P8/02
Filed: 1980-05-28
Abstract: PURPOSE:To reduce the useless loss of energy and increase the efficiency of driving energy, by opening a motor coil for the period during which no driving force exists in a stepping motor under driving. CONSTITUTION:A prescribed division-stage output is applied to a shaping circuit 4 from a divising circuit 2 to produce a pulse S1 covering over a chopper driving period and a fractionated chopper driving pulse S2. And the waveform of a driving current Iu is formed by the chopper driving period T1 and the intermediate period T2. During the period T1, both pulses S1 and S2 are at a high level, and the outputs of AND gates 6 and 7 plus 5 and 8 are set at a high level and a low level respectively when the output Q of a steering FF which reverses the driving polarities alternately is set at a high level. Thus transistors 11 and 12 are turned on to apply the driving voltage to a driving coil 14 of a step motor. On the other hand, the coil 14 is also opened in the period during which no driving force of the period T2 exists. Thus no damping or the like is carried out for a stator to reduce the useless loss of energy. As a result, the efficiency of driving energy is increased.

Title: Heat-resistant steel for engine valve
Inventor: SATO KOJI
IPC: C22C38/00
Filed: 1990-03-20
Abstract: PURPOSE:To permit heat treatment to the heat-resistant steel at a temp. equal to the solid solution heat treatment in a 21-4N steel and to combinedly provide the heat-resistant steel with excellent high temp. strength as well as corrosion resistance and oxidation resistance same as those of a 21-4N steel, in a high Mn series heat-resistant steel having a specified compsn., by regulating the content of C to a minimum and combining the interaction of W with N as solid soln. strengthening elements. CONSTITUTION:The heat-resistant steel is constituted of, by weight, 0.01 to <0.20% C, 0.05 to 1.0% Si, 7.5 to 15.0% Mn, one or more kinds of Ni and Co so that 2.0 to 20.0% Ni+Co is satisfied, 15.0 to 25.0% Cr, >2.0 to 10.0% W, 0.01 to <0.50% Nb, 0.30 to 0.65% N, <=0.02% B and the balance Fe. In the steel, as for C, the quantity of the lower limit is at least required for improving its strength; as the increase of its quantity, the quantity of carbide to be formed increases, and in the case of more than the upper limit, the solid soln. of carbide is not sufficiently formed at the solid soln. heat treatment temp. of the low temp. of about 1050 deg.C, it is not effective for its creep strength and the solid soln. degree of N is deteriorated. Ni and Co are required by the quantities more than the lower limit for maintaining its strength, corrosion resistance and oxidation resistance, but if they are too much, the solid soln. degree of N is reduced and the steel is made expensive. W is an interstitial solid soln. strengthening element and moreover improves its high temp. strengthening by the interaction with N.

Title: El display device
Inventor: YOKOTA MINORU
IPC: H05B44/00
Filed: 1993-03-30
Abstract: PURPOSE:To fairly prevent noise without extending a device in an EL display device which displays various picture data by controlling the light emission of each picture element constituted at each intersections of multiple scanning electrodes and multiple data electrodes which are orthogonally intersected with the scanning electrodes. CONSTITUTION:Pulse voltage -VH is applied to the scanning electrode Y1 of a first row, in the same way, pulse voltage VH to the scanning electrode Y2 of a second row, and pulse voltage VM to the data electrode X1 of a first column respectively, at the time of t0-t1. Voltage VH+VM being larger than a threshold value Vt is applied to the picture element Z11 of the first row and the first column, and a EL light emitting layer emits the light. Since voltage having inverted phases each other are applied, vibration of the EL light emitting layer owing to that voltage interferes each other. Therefore, the vibration of whole EL display device is reduced, and noise can be fairly prevented.

IPC: G03G21/08
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device in which a damage to a photoreceptor, that caused by toner and carrier adhering to the photoreceptor at the time of all fault generations excluding an operation fault of an exposure light source and at the time of a restart after these faults are released, is prevented, safety of the body is secured and working efficiency is made superior.

Thus, as shown in a chart L, since the electric charge residual region on the surface of the photoreceptor is discharged, the residual charge is surely discharged without providing an additional discharging means. Moreover, the working efficiency of the device is greatly improved.
